Where do foreigners usually stay when they go to Seoul for beauty treatments? 🧴

Hey everyone! My name is Huong, and I'm from Vietnam. I'm planning a trip to Seoul next month to try some beauty treatments, but I'm a bit confused about where to stay. I've heard that Gangnam and Apgujeong are both "hot" areas for aesthetics, but I'd like to ask those of you who have been there before – have any of you stayed in these areas? What was it like? Was it safe?

I'm interested in choosing an area that's close to beauty salons, has plenty of good restaurants, and is easy to get around. Does anyone recommend accommodation that's "good for tourists"? I'm not sure whether to stay in a hotel, Airbnb, or anything else. My budget is moderate, not too high, so I want to optimize a bit.

One more question – for those of you who have gone to Seoul for beauty treatments, did you feel you needed to learn basic Korean? Or is English enough? I'm a little worried about communication. Thanks a lot! 😊
